[Hackrf-dev] Jawbreaker firmware update fail

[hackgnar]

Graham,

I think you may just be stuck on a bad flash.  The first time this happened to me, I had to bang my head on the table for a few minutes.  These are the detailed steps on how to recover.

1) Following the steps on the wiki firmware section, I unplugged the hackrf, shorted the two pins to enter DFU boot mode and then plugged in the board with the pins still shorted.

2) I ran "make program" from inside the hackrf_usb directory.  I got stuck here as I didn't have the program "dfu-program" installed.  After installing this I was fine.  You'll obviously also need other build dependancies up and running.  The trickiest being  https://code.launchpad.net/gcc-arm-embedded , but you can read the readme.md located here https://github.com/mossmann/hackrf/tree/master/firmware

3) After running "make program" successfully, you can then change into the hackrf_usb_rom_to_ram directory, compile the hackrf_usb_rom_to_ram.bin file and install it with: 
hackrf_spiflash -w hackrf_usb_rom_to_ram.bin
This assumes you installed hackrf_spiflash to your base bin directories.

Let me know if you need any more help.

Ryan
